here is a question for those 'in the know' about tyres

my da9 came stock with 195/60/14's

i purchase some civic vti-r wheels with 195/50/15 tyres

it has come time to replace the front tyres (the back still have a little tread, but probly no more than 5000kms worth)

i SHOULD have 195/55/15's to keep the same rolling diameter, but this would mean different profile on front vs rear.

i am not particularly concerned by my speedo being off, as it is only a very smaller amount, and it shows me going faster than i actually am, so no risk of speeding fine

what are peoples thoughts on whether it would be better to replace the fronts with 50 or 55 profile tyres?
